Application filed October 2, 1912. Serial I11 0. 723,542.

To all whom it may concern:

Be it known that I, PLEASANT A. HUD- nLEsToN, a citizen of the United States, residing at Oklahoma, in the county of ()kla homa, State of Oklahoma, have invented certain new and useful Improvements in Electric Annunciator and Lighting Mechanism; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in'the artto which it appertains to make and use the same. This invention relates to a combination electric alarm or annunciator, and electric lighting mechanism designed especially to be installed in hotels, apartment houses and residences, although it will be understood that it may be employed in any connection where its use will be found advantageous.

In carrying out my invention it is my purpose to provide an electrically operated apparatus which embraces an alarm, such as abell located, for instance, in a guest room in a hotel, an electric lamp forming a part of the lighting equipment of such room, and a switch board located at a suitable lace in the hotel, for instance, the central 0' cc, said switch board bein under control of an operator. The usua wall switch Within the feet understanding may be had of the invention as hereinafter described in detail I will state briefly the purpose of the invention,

Should a guestof the hotel desire to be called at a, selected hour, say seven oclock a. m., the switch board operator is given notiee-of the fact. At this hour the operator at the switch board throws a switch belonging to and preferably. correspondin in number with the room. The e ectric light of the room is of course presumed to have been cut off when the occupant retired, and the closing of the operators switch results in sounding the alarm bell in the room and lighting the electric lamp in such room. At the same time 'a small pilot lamp above the particular switch is h hted showing that the alarm has been soun ed and the lamp in the room ignited; At this time the Whole current does not flow to the lamp in theguest room, as part of the same is shunted to .ing provided with a small electric lamp the bell mechanism for ringing the latter so I that the lampjn the room' burns but dimly. When the guest has been aroused he pushes the wall switch to turn the full current into the lamp so that'the latter will burn at full capacity, and this act of shunting all the current to the lamp cuts out the bell so that the alarm is silenced and at the same time the ilot light at the switch board is extinguis led, notifyin the operator that the call has been receive It is also my purpose to provide an alarm and lighting system which will embody the desired features of simplicity, efiiciency, re-

liability and convenience, and which maybe readily. installed in a hotel at "a'l'olatively low cost in as much as it is unnecessary to disturb or change the electric wiring system of the house.

With the above recited objects and others of a similar nature in view, my invention consists in the construction, combination and arrangement'of parts set forth in and falling within the scope of the appended claims,

I In the accompanying drawing the figure illustrates diagrammatically one embodicates'the usual wall switch of the room by means of which the light is turned on and off. In the present instance the switch board A is equipped with twenty-five individual switches 4, this being designed for a hotel havingtWenty-five guestrooms. These switches are preferably in the nature of single-throw three pole switches, each switch be or pilot light 5. The numeral 6 designates a conduit or casing for containing the wires leading from the various rooms to the switch fromthe conductor 2 to the pole 12 of the wall switch 3, while 13 is a branch wire lead ing from the switch pole 12 to the binding post 14 of the hell. 1

Presuming the wall switch to be ofi', to cut in the-lamp G at the selected hour the operator throws on the switch 4 at the switch .board'. This results in the current from the line 1 passing through the light C, thence through the wire 10 leading to the switch 9, thence through. the branch line 8 and through the switch lighting the pilot light 5,.

thence through the line 7 to the bell, ringing the'latter said current .then flowing through the branch wires 13 and 11 to the return line 2. vWhen the guest throws the room switch after rising in response to the'alarm,

' the full current passes through the lamp 0,

f I lamp orpilo't light will burn onlywhen the through the branch wire 10, thence through the wall switch in the usual manner-and back.

through the line 11 to the return line 2. Thiscuts'ofli' the current from the bell and the switch board and the extinguishing of the pilot light 5 notifies the operator that the call has been received, and the switch maybe restored at the switch board to its normal cut out position. It will thus be noted. that when the operator throws the switch to call the occupant of. the room not only is the light turned on and the a arm bell sounded, but the small signal or pilot light at the switchboard is lighted and willv continuefto signal so long as the bell is ringmg. When'the guest throws the switch in the roomthisextinguishes the l' ht at the switch and stops the alarm, but eaves the light in the room burning at full capacity.

Therefore the operatorhas 'proof that the roomer has been awakened, as the signal alarm is sounding.v

. Another advantage incident to my invention is thatshould the guest go out and leave' the light burning in his room this may be r ascertained by the operator simply throwing the switch at the switch board. Should the pilot or signal light show up it notifies the operator that the li ht in the, room has been extinguish ed, but s ould the signal-or pilot light .fa-il tolig'lilt' up then the operator knows that the room lamp has been left burning.

'1 hus an important saving in the consump-f t1on of current may beihad by promptnotiee being given; This is a considerable item in large hotels, containing hundreds of rooms, as guests frequently leave their rooms, leaving the lights burning for hours needlessly.

While I have herein shown and described one particular embodiment of my invention, I wish it to be understood that I do not confine myself to all the precise details herein set forth as modification and variation may be made without departing from the spirit of the invention, or exceedingthe scope of the appended claims.

What is claimed is: 1
